Replace or Repair?

Buying a new heating system is a major investment. It's often worth your while to maintain and repair your old system until it's necessary to replace it. However, if your furnace is more than 12 years old, upgrading to a high-efficiency furnace will save you energy and may save you money. That's because older furnaces tend to run at about 60 per cent AFUE*, whereas new high-efficiency furnaces run in the 90 per cent - 97 per cent AFUE range.

Regular inspections and maintenance help to keep your heating system operating safely at its original efficiency level. A licensed & registered gas contractor should inspect and service your heating system at the intervals recommended in your owner's manual.

*AFUE stands for Annual Fuel Utilization Efficiency. It's a measure of how well an appliance converts fuel into heat. If your furnace has an AFUE rating of 90 percent, which means that 90 cents out of every dollar you spend on fuel ends up as useful heat.
